Given that the lowest energy state is a 3P state, according to selection rules for electronic transitions, a possible set of correct energy levels (X, Y, and Z) is:
- 1X = 3P1, Y = 3P2, and Z = 3D1
- 2X = 3P2, Y = 3D1, and Z = 3P1
- 3X = 3P1, Y = 3D1, and Z = 3D2
- 4X = 3D1, Y = 3P1, and Z = 3D2✓
Correct answer
X = 3D1, Y = 3P1, and Z = 3D2
